To all whom it may; concern:

Be it known that 1, WILLIAM W. SWEET'- ftfiivn, a citizen et the United States, residing at Edwardsburg, in the, county of Cass and State of Michigan, have invented a new and yusetul Sash Supporter Lock, of which' the following is a specification.

The'objects of the invention are, the provision, in a novel and improved form, of a sash supporter and lock, which shall be inexpensive to manufacture, facile in operation, and devoid of complicated parts, other objects and novel features of construction being disclosed as the description of the invention progresses.

The invention consists in the novel construction and arrangement -ot' parts, hereinafter described, delineated in the accomi panying drawings, and particularly pointed out in the appended claims, it being understood that divers changes in the forni, proportions, size and :minor details oi the struc ture may bel made without departing from the spirit or sacrificing any 01' the advantages of the invention.

Similar numerals of reference are einthroughout the several figures of the drawings.

ln the accompanying drawings z-Figure 1 is a front elevation of a Window sash of conventional construction, with the sash lock and supporter of my invention attached thereto; Fig. 2 is a rear elevation of the invention, a portion of the levers 6 bei-ng broken away better to illustrate the structure; Fig. 3 is a side elevation; Fig. 4 is a top plan, the housing 1 being broken away, more clearly to reveal the internal structure of the device; Fig. 5 is a detail perspective of one of the levers 6.

To enable others skilled in the art to which the invention appertains, to make and use the saine, l' will now describe its conthe same is carried out.

The invention comprises a housing 1 which maybe of any Jform; as shown, it is box-like in structure, open at the back, and provided with straight rear faces 4, extending outward beyond the -top and bottoni of the housing 1A The housing l is provided with alined open ings 2 in the top and bottom. Other `openings 3 are provided in the side of the' housing i l, and upon the opposite side are located the l ylevers 6 prevents the spring 14 from being openings 5, which are wedge-shaped in their preferred form, as shown in Fig. 3.

Referring to Fig. 5, it will be seen that the levers 6 comprise a wedge-shaped end 7 adapted to register with the openings 5 in the housing 1. The body 8 of the llevers 6, is in the forni olE a parallelograni, and by this construction, a shoulder Q is provided, outstanding beyond the wedge-shaped end 7 and arranged to contact with the interior of the housing 1. -T he yendl() of the levers 6 which is arranged to move in the openings ,3 of the housing 1, is similar in shape to the end 7, and from this end 10 projects outward through the openings 3, the thumb pieces 11, whereby the said levers 6 may be operated. The levers 6 bear openings 12, alined With each other, and with the openings 2 in the housing 1. A rod 13 is slidably mounted in the openings 12 and 2, and acornpression spring 14 encircles the rod 13, the said spring having its ends in contact with. the adjacent faces l5 of the levers 6.

The shape of the body portion 8 of the moved laterally into contact with the rod 13 when the levers 6 are operated, increasing the force necessary to operate the device, a contingency which. would occur if the wedgeshaped constructionof. the ends 7 were carried through the entire length of the lever. The shoulders 9 serve to hold the levers in proper position and prevent them troni Inoving into lrictinal contact with the rod 13 when the thumb-pieces 11. are pinched toward each other.

The operation ol the device is obvious; however, it may be noted that, While parallel laces 15 are provided upon the levers 6, agains which the ends oi' the spring 14 may bear when the levers 6 are brought together, the ends 7 arewedge-shaped. By this construction, when the levers 6 are allowed to separate under the action of the spring 14,'

the said levers 6 will have their faces 16 tilt 10G.

ed slightly toward each other increasing the grip of the lever 6 upon the rod 13.

ln practical operation, the levers 6 maybe pinched together and the sash supporter and lock slid up or down the rod 13 with the sash, 10

in the ordinary manner. However, by the'- pcculiar construction oi' the levers 6 hereinl-fclore described, l am able to provide a de vice which, While atfording a secure lockiis delicate and sensitive in its operation.

' l the Window sash will slide slowly down under the friction of the lower lever, and if the nger be placed beneath the lower lever 6, the

Y housing having` wedge-shaped slots in one of nal arranged to register with one of the v y Contact With the interior ol' the housing.

the finger be pressed1` upon the upper lever 6 l Window may be raised against the friction of the upper lever 6.

Having thus described my invention, what I claim as new and desire to protect by Letters-Patent, is

l. .In a device of the class describedI a ,2, In a device ol the class described a housing having in one of its sides, Wedgeshaped slots, and in its top and bottom, I alined openings; levers mounted in the hous- I ing, the said levers being provided With ivedgefshaped terminals arranged to'register with the Wedge-shaped slots in the housing, and having openings alined With .each other and With the openings in the top and bottom l of the housing; 'a rod slidably mounted in the alined openings in the lever and inthe housing; and resilient means for separating the.

levers. Z

3. In a device of the class described, levers comprising a rectangular body portion and a Wedge-shaped terminal integral With the body portion; a housing having Wedge' shaped slots arranged to receive the terminals of the levers; and resilient means for separating the levers.

In testimony that I claim the foregoing as my ownJ I have hereto alixed Ury-signature in the presence of two Witnesses.
